High anion gap metabolic acidosis in adults is a severe metabolic disorder for which the primary organic acid usually is apparent by clinical history and standard laboratory testing. We report a case of recurrent high anion gap metabolic acidosis in a 48-year-old man who initially presented with anorexia and malaise. Physical examination was unrevealing. Arterial pH was 6.98, P co 2 was 5 mm Hg...

Diabetic ketoacidosis (DKA) is characterized by excessive production of organic acids leading to a low blood pH. Rarely, because of other complicating factors blood pH may be in the alkalemic range and the term diabetic ketoalkalosis has been coined to describe this condition. So far, less than 30 such cases have been reported in the literature. We report a 34-year-old woman who received methyl...

In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the Ag(I) atom is coordinated by four P atoms from triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The anion and solvent are engaged in weak O-H⋯O hydrogen bonds. Of the four triphenyl-phosphane ligands, two each have an equally disordered phenyl ring while the Ag(I) atom is disordered over two positions in a 0.9595 (1...

In the title compound, [Ag{P(C(6)H(11))(2)(C(6)H(5))}(2)]ClO(4)·CH(2)Cl(2), the Ag(I) atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag-P = 2.3993 (4) and 2.4011 (4) Å; P-Ag-P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯O(perchlorate) inter-action of 2.873 (2) Å, which contributes to the slightly non-linear...

The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third oc...

The anion gap in the serum is useful in the interpretation of acid-base disorders and in the diagnosis of other conditions. In the early 1980s, ion-selective electrodes for specific ionic species were introduced for the measurement of serum electrolytes. This new method has caused a shift of the anion gap from 12±4 mEq/L down 6±3 mEq/L. It is worthy for clinicians to understand the range of nor...

INTRODUCTION To investigate whether the difference between sodium and chloride ([Na(+)] - [Cl(-)]) and anion gap corrected for albumin and lactate (AG(corr)) could be used as apparent strong ion difference (SID(app)) and strong ion gap (SIG) surrogates (respectively) in critically ill patients. METHODS A total of 341 patients were prospectively observed; 161 were allocated to the modeling gro...

In the title complex, [Ag(C(16)H(14)N(2))(2)]NO(3), the geometry around the Ag(I) ion is T-shaped with two short Ag-N bonds to the pyrazole ligand and one long Ag-O bond to the nitrate anion. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯O and C-H⋯π inter-actions.

Pesticide formulation includes solvents (methanol and xylene) and antifreeze (ethylene glycol) whose metabolites are anions such as formic acid, hippuric acid, and oxalate. However, the effect of the anion gap on clinical outcome in acute pesticide intoxication requires clarification. In this prospective study, we compared the anion gap and other parameters between surviving versus deceased pat...

Lower levels of serum bicarbonate and a higher anion gap have been associated with insulin resistance and hypertension in the general population. Whether these associations extend to other cardiovascular disease risk factors is unknown. To clarify this, we examined the association of serum bicarbonate and anion gap with cardiorespiratory fitness in 2714 adults aged 20-49 years in the 1999-2004 ...
